Monster will be a 21 run for you and with your size boat you’ll need to pick your days. Best to start early and come home before the afternoon winds pick up which could make for a nasty ride home. Bluefin Tuna are hit and miss and Mahi are fairly consistent once the water temps rise into the mid 70s . Your best bet for Mahi is going to be working and trolling the Lobster post and the last few seasons there have been more pots on the western side of the Mudhole and the monster is on the east. If you want to target Mahi, I’d head out to the Shark River Reef which is just inside western edge of the Mudhole and run the pots north of there.
Here’s a post specific to small boats and Mahi
